14 // chip.
15 //
16 // @brief
17 // Implement a basic IO library to drive the PCF8574* I2C IO Expander ASIC.
18 // The library implements basic IO general methods to configure IO pin direction
19 // read and write uint8_t operations and basic pin level routines to set or read
20 // a particular IO port.
21 //
22 // @version API 1.0.0
